 The highlight of this run was the 4th Round game against Manchester City on 27 January 1974, when he made three goals and scored the fourth in a 4–1 thrashing of the First Division giants.This was probably the greatest game of his career, but he seldom hit such great heights again, despite many sublime moments subsequently.McKenzie was signed for Leeds United by Brian Clough during his 44-day reign as manager of Leeds, and was the only one of his signings to subsequently flourish at the club.
